Subsection Optimization of MV Distribution Network Based on LCC and DPSO Algorithm
Based on LCC,this paper establishes a subsection optimization model which includes reliability cost and reliability benefit when sectional switches are connected into main feeder in MV distribution network.The effects of sectional switches allocation on the reliability of distribution network are analyzed in detail,and the recursion formula of outage loss decrease is proposed when the sectional switch is added one by one.The discrete particle swarm optimization (DPSO) algorithm is introduced for optimization.The principles of mutation and crossover operator in genetic algorithm(GA) are adopted to DPSO algorithm to achieve better diversity and avoid local optima.The tests on IEEE RBTS-BUS6 and other distribution systems for sectional switches allocation show that with the expansion of network,the proposed method is obviously superior to other optimal algorithm in optimization probability and precision.
